Environmental Industrial Water & Algae Control

Waste water represents a significant strain for the natural environment. Such waste water is produced in significant quantities by large numbers of industries, Households, and the public at large.

To avoid releasing this water straight into the environment, complex and technical systems of water treatment are been used.

However, these processes themselves produce their own waste and use up significant amounts of chemicals and energy.

ASM sonic wave technology (ultrasonic based oxidation) offers the possibility for dramatic efficiency gains in the process of treating waste water, reducing the chemicals needs of the process whilst simultaneously increasing the performance of all traditional and curent procedures.

Our engineers and partners have designed our products for your individual needs and purposes. We have researched over the past decade and continue to research and develop our sonic devices with customer satisfaction as the pinnacle driver for achievement..

Bio film is a fast growing, structured community of uni cellular organisms that adhere to surfaces that are submerged in or exposed to water. Algae live within this bio film. This includes commercial applications where green algae and filamentous algae can create a lot of problems and add a great deal of expense to keeping it under control.

Wastewater Application

Wastewater is any water that has suffered in quality by human intervention. Often, wastewater is being treated for re-use as drinking water or for other purposes. As high levels of nutrition are available in these waters, algae may grow rapidly as well as other micro-organisms such as bacteria. Algae can compete for nutrients against the bacteria in charge of sludge reduction and can also clog complete systems. uses the newest ultrasound techniques to remove the threat of algae from wastewater treatment plants and reclaimed water reservoirs.

A research project executed to study the effect of ultrasound in the treatment of wastewater was the Chem-Free project.

Briefly, some of the results achieved in wastewater applications using the ultrasounds systems are:

• Strong reduction in algae concentration (± 90% reduction of chlorophyll-a)
• Reduction of biofilm formation
• Reduction of TSS, turbidity, BOD, COD levels etc.
• Reduction of free bacterial counts (E. coli, Enterococci etc.)
• Ultrasound vibrations make it more efficient for bacteria present in the sludge to obtain nutrients, and speeds up the utilization of nutrients, accelerating the degradation of organic waste and the consumption of nitrate and phosphates.
• Secondary effect, improvement of the UV/ozone performance in elimination of microorganisms

Settling lagoons and ponds

This is another important location where we could realise excellent benefits by installation of ASMP-1000 systems.
These ponds are characterised by large open lagoons with a fairly high residence time of water and UV exposure in the summer months.
During the holding period in the open reservoirs, filamentous algae start growing along with other bacteria and fungi can create in most cases strong foul odors .
Very often these ponds use aerators, nurture fish culture which consumes some of the algae produced.
However, only having fish and aerators in the ponds is most of the time not adequate to control the microorganisms and algae.

To inprove the water clarity so to prevent the development filamentous algae on the lagoon surface and to control the unwanted smell etc., ASMP-1000, fish and aeration facilities are combined to achieve the best environmentally results.

ASMP series provide a multifaceted approach to algae control in water treatment while maintaining an ecologically friendly approach. In addition, installations have shown that elements such as total suspended solids,filamentous algae, nitrates, phosphates and chloride/chemical use will be reduced

The Benefits

ASMP equipment can be locally proggrammed to suit different process applications needs.
From our previous experience we could safely assume a reduction of chlorine consumption by about 30-50% at the final chlorinate doseage treatment stage.
Using ASMP in treatment stages with UV & aerate and gloiride treatment will achieve a much better result before releasing water in to lakes or river.
Environmentally friendly as there are no pollutants associated with this method of removing algae and filamentous weeds.

The presences of soluble organic material as well as high concentrations of suspended matter in waters and wastewaters affect the efficiency when chlorine is used as disinfection agent.

The objective of our work is to explore to which extend ultrasonic treatment can facilitate wastewater disinfection with chlorine in order to bring down doses of ecologically questionable chlorine and to shorten contact times.

Sewage treatment plant (STP) effluents with different concentrations of suspended solids are exposed to sonication in combination with chlorine dosage. We observed that enhancement of chlorine efficiency is better for samples with higher concentrations of suspended matter.

For samples with a TSS concentration of 50 mg/L chlorination efficiency (2 mg/L) can be doubled from 0.7 to 1.4 log when treated simultaneously with asmp-100.1 -2005 ultrasound for 5 minutes, i.e. levels of indicator organisms can be brought down to numbers that conventionally require far higher doses of chemical disinfectants. As subsequent sonication/chlorination does not have the same significant effect as simultaneous application of these two means, ultrasound does not just have a DE clumping effect; it seems that ultrasound application provokes better chlorine dispersion in the aqueous media which improves the fast chemical and bactericidal reaction
