Aqua-PhyD, Inc. is based in Irvine, California. The Company has developed a non-chemical water and soil treatment technology that addresses water shortages and water quality issues.

Aqua-PhyD was founded in 2004 with a "Green" company water conservation agenda. However, understanding the need to prove its business model and technology in a clearly defined market, the Company first targeted the high profile US Golf industry where significant volumes of fresh water are used daily.

Today, the Aqua-PhyD technology is in use on several golf courses. Each course has demonstrated a reduction in soil compaction, saving on water consumption, and conspicuous, visual evidence of greener, healthier turf.

In 2007, Aqua-PhyD entered agriculture enabling growers to stretch limited water supplies. In addition, Aqua-PhyD has proven to provide a number of benefits to agriculture leading to healthier plants, increased nutrient availability, decreased salt accumulation, and greater yield.

Following the success of university studies exploring Aqua-PhyD’s treated water on pipe corrosion, the company began providing solutions for various industrial applications including boilers and chillers and power plants. It is the newest addition to the growing list of divisions for the Aqua-PhyD technology.


        AGRICULTURE

The Aqua-PhyD system enables Agriculture to:

  • Save water
  • Prevent salt accumulation in the root zone
  • Reduce effects of reclaimed poor quality water
  • Increase nutrient availability
  • Reduce compaction

Soil samples were taken at a California vineyard. After 75 days of treating the soil with

Aqua-PhyD, new soil samples were taken. Note comparisons between blocks 25 and 26.

NON-TREATED   TREATED

Moisture Retention in Soil

A study was performed on a tomato field using a subsurface drip system. The average depth of tomato roots is 3 to 4 feet; tomatoes drink water in a reverse pyramid (1st foot-40%, 2nd foot-30%, 3rd-20%, 4th-10%). The water supplied to the field had over 1200 ppm in Total Dissolved Solids (TDS), affecting water infiltration and percolation.

Monitoring sensors were set at 8 inches (red), 16 inches (blue), and 24 inches (green) on two Blocks: Control (Non-Treated) and Aqua-PhyD (Treated).

Study results:

  • The Aqua-PhyD Block consumed 29% less water per acre than the Control.
  • The Aqua-PhyD Block had greater moisture at all three sensor levels making water uptake more available to the plants.

Growing a Corn crop with 30% Less Water

In the picture above, the sweet corn to the left of the yellow line was watered using a recommended schedule and watering amounts for the area. The corn to the right of the yellow line used the same watering schedule but received 30% less water from germination to current growth than the corn to the left of the line.

California State University, Fresno and the Center for Irrigation Technology (CIT) Study

Study: Interaction of Aqua-PhyD Treated Water for vegetable production (Broccoli) using 20% less water.

     In Clay Soil:

  • Treated water had significant effect on broccoli floret size
  • Floret sizes irrigated with 80% ET were similar to 100% ET
  • Treated plants matured earlier

     In Sandy Loam Soil:

  • Treated water produced a comparable crop despite a 20% water reduction

                  

"Broccoli plants watered and grown in clay soil at 100% ET, when exposed to the Aqua-PhyD treatment, developed earlier. At 80% ET, the Aqua-PhyD treated plants produced a plant equivalent in size to the plants watered at 100% ET. This finding is important since growers with salt affected clay soils are continuously seeking out irrigation technologies which will improve the growth rate and thereby result in an earlier crop harvest date."

Growing Plumerias with 40% Less Water and Increased Yield

Aqua-PhyD treated water accelerated growth and produced a healthier plant. Leaves are 9 to 12 inches in length with early flower blooms (Treated) compared to 2 inches without Aqua-PhyD (Untreated). Non-Treated plants pictured below left. Treated, below right.

"Using normal water, soil and fertilizer procedures, my plants will grow 8 to 10 inches of new growth each season. With Aqua-Phyd I have 18 inches of new growth with a healthier plant using no fertilizers. I have happy plants." - Plumeria Nursery owner

     GOLF and TURF

How much water you have to put on your grass and soil is not as important as how much water gets into the soil. Compaction is the enemy. Golf carts, golfers, chemicals, reclaimed water, wind, heat, and even heavy raindrops will compact soil and prevent water from penetrating the soil. Compaction causes runoff, standing water, yellow and brown spots. Compaction denies water penetration to needy roots that grow a healthy plant.

Aqua-PhyD guarantees significant and sustained compaction reduction on any golf course or park with normal irrigation. Not only will compaction be reduced even in hard clay on a hot summer day, once the water has penetrated to the roots, the moisture will remain. Surface evaporation, runoff and standing water will be eliminated. As a final benefit, water use and its related cost will also be significantly reduced.

Compaction readings at four sample courses started with readings between 600 and 800 psi. Before treatment, the meter was unable to penetrate more than one inch.

Within six days compaction was reduced to the 200-250 psi range and probe penetration increased to 10 inches and more using Aqua-PhyD.

Chart

Compaction levels at The Palms Country Club, La Quinta, CA were 720 psi. Within one week of water and soil conditioning, compaction levels dropped to 220 psi and the compaction meter easily penetrated the soil to a depth of 18 inches.

 

Golf Installations

Aqua-PhyD's technology installs into the main water supply line. Water is treated using only the normal irrigation water pressure and flow. A sampling of installations are pictured below.

 

 

 

A side benefit of using Aqua-PhyD is that irrigation pipes and drip systems are continuously cleared of calcium and chemical buildup. The following picture shows pipe buildup, cleaned from the pipe and captured in the sprinkler-head filter.

Case Study - Growing Push-up Greens with 20% Less Water

Desert Forest Golf Club in Carefree, Arizona

A split nine trial was performed over a 60-day period with the following results:

Water Penetration - "From the beginning, we saw better water penetration and a better root mass. Also, a better secondary root growth. We went from a dispersed soil to a flocculated soil where we got better use of our nutrients and minerals in the soil."

Nutrient Availability - "Base saturation tests found that nutrients were much more available to the plant."

Increased Root Growth - "We saw an increase in the root depth and root mass. Before we only got 1 to 2 inches. Now we are getting 3 to 4 inches. The secondary growth has changed resulting in a better uptake of moisture and nutrients to the plant where the plant is much fuller and has a better capability to go through the drought so we won't have to water as much."

Leaching of Salts - "It was dynamic to see the magnitude of the change in the black clay layer. We were also able to get better leaching to take place moving the salts and bicarbonates out of the root area which gave the plant the ability to grow."

Water Savings - "The turf is in as good a shape, if not better with a 15% to 20% water reduction."

The chart above represents the average composite for the front and back nine with all 18 greens being tested. The nutrients are expressed in part-per million (ppm) with the resulting increase in solubility. This evaluation resulted with the installation of the Aqua-PhyD system and brought about reduced compaction, improved playability and turf grass vigor. After rain occurrences, it was noted that certain areas prone to ponding due to compaction no longer had standing water.

       INDUSTRIAL

Following a successful university “proof of concept” study exploring the effect of Aqua-PhyD’s treated water on pipe corrosion, the Company began developing solutions for various industrial applications including boilers, chillers and industrial cooling water.

Aqua-PhyD has developed a pipeline of projects in the commercial real estate and large facilities such as airports for cooling water applications for air conditioning. The company is marketing a totally “green” solution that will lower costs, water use and chemical use for cooling water applications.

Industrial Benefits

The opportunity in the industrial market is driven by specific water management requirements.  Cooling tower vendors recognize the critical nature of managing corrosion and scale by providing specific “Water Quality Guidelines” for the operation of their equipment.

By effectively managing corrosion, the cycles of concentration can be increased resulting in a significant savings from water use.  The following spreadsheet sets forth the water usage characteristics of an 8,000 ton cooling tower at a range of cycles of concentration:

The Aqua-Phyd system can dramatically improve the energy efficiency of cooling tower systems through the reduction of scale and corrosion.  A Federal Technology Alert issued by the DOE set forth the following estimates for increased energy consumption based on the build-up of scale:

Energy Efficiency Opportunity

A cleaner system will be able to transfer more heat.  Water temperature going to the cooling towers and leaving the heat exchangers after releasing its heat is referred to as the “Delta-T” – the smaller the gap, the more efficient the heat exchange.  APD will measure and record actual corrosion and fouling rates before and after installation.

Operating Costs & Maintenance

APD’s industrial system provides the opportunity to eliminate certain chemical usage and avoid the requirement to shut-down for maintenance.

* pH Control and Biocides will still be required (although reduction of biocide is likely and/or ability to use inexpensive alternatives such as chlorine bleach or a mechanical solution – see below).

* Ability to eliminate or reduce use of corrosion inhibitors, anti-scalants and dispersants.

* Shut-down for cleaning and scrubbing maintenance will be dramatically reduced or completely eliminated.

Extending the useful life of equipment can provide significant capital expenditure savings (savings estimate assume 10% discount rate and straight-line depreciation over the useful life):

The following chart illustrates the ability of the Aqua-Phyd technology to effectively control steel (and bronze) corrosion in cooling towers.  Data was collected during a six month trial at a large hotel.
