Hydroxypure Water Sanitation System for Farming by Waterco

Day 14: Compare roots condition; Left: control set of full algae, roots seem healthy. Right: Hydroxypure set no algae, roots seem healthy.

Australian invention helps feed Malaysia's masses - Waterco's Hydroxypure boosting the farming and hydroponic sectors.

The Cameron Highlands is situated in Pahang, West Malaysia, approximately 85kms from Ipoh and about 200kms from Kuala Lumpur. At an elevation ranging between 1135 metres to 1829 metres above sea level, it is the country's highest point accessible by road.

Considered the epicentre for Malaysia's vegetable and flower farming sectors, the region is famed for its lush, fertile soil, cool climate, steeply farmed hillsides, tea plantations, and sprawling strawberry farms.

In the midst of this is Cameron Highlands' hydroponic lettuce farm, which has become a popular tourist attraction since opening in 1990.

Challenges

Hydroponics is a branch of agriculture where crops are grown in water instead of soil. Depending on which of the six types of hydroponic systems are used - Drip, Ebb and Flow, NFT (nutrient film technique), Wick, Water Culture and Aeroponic - the plant's roots are either suspended in, flooded with or misted using a nutrient-rich solution that enables the plant to grow.

"The challenge with this massive farm involved the open water races and drains, which is essentially a network of long channels where each lettuce is individually grown and fed," explains Hydroxypure inventor Nick Briscoe. "The channels were filling up with algae and, when lettuce gets bacteria in it during the propagation phase, it dies very quickly once it's picked."

A further challenge involved the lack of quality starting water in Malaysia. Domestic sewage, livestock farming and other liquid organic waste products are said to be responsible for a large number of polluted waterways throughout the country.

Surmises Nick: "So we had three challenges to address - one was cleaning up the water races as they were getting clogged up with algae, two was creating a healthier lettuce that would last longer after it was picked, and three was improving propagation time."

Objectives

Two trials using Waterco's Hydroxypure filtration system were set up using food grade H2O2 at 35 per cent: Trial 1 was small scale with 100 crops, while Trial 2 involved a larger scale involving 16,000 crops spread out over one acre.

With both trials, the objectives were as follows:

To compare growth rate with control set;
To compare disease/mortality rate with the control set; and
To prevent algae from growing in the hydroponics channels and drains.

"The first thing that happened was that we fixed the problem in the water races, so they were all clean and free of algae," Nick explains. "The second significant thing that happened was that propagation went from 55 days down to 31 days."

Benefits

Hydroxypure's hybrid ozone technology stimulates the action of the sun by generating a high-intensity wavelength of light, which in turn produces a clean form of ozone that is free of impurities. The natural flocculating effect that ozone has on water greatly increases the capability of the filtration system to be able to filter out oxidised contaminants in the water, leaving hydroponic water clean and crystal clear.

"Hydrogen peroxide, which is hydrogen and oxygen, does not form any by-products when you're adding other chemicals," says Nick. "This enabled us to achieve positive results on the hydroponic farm without upsetting the other growing systems."
