What our Clients say

Algae was causing water quality issues for a council in the North Island, and algae was not wanted in their water bodies because it can cause odour problems, it is not aesthetically pleasing and some types of algae produce toxins and are poisonous to animals.

An Ultrasonic Algae Control Device was installed with excellent results.

“Algae growing in the council’s 2.1 hectare reservoir has withered and died within a month of being hit by ultrasonic soundwaves. It’s the first time we have used soundwaves to control algae and the trial has been a resounding success” said Mark, the council’s manager of water.

Mark continued “It works on certain types of algae and basically it damages the cell structure in the algae and they die. After a month we found the algae was indeed dying off, which is great because there’s no chemicals and it doesn’t kill fish. The technology has been around for some time and the frequency of the ultrasonic soundwaves are very high and above what a human ear can hear. It saves using other methods, like chemicals, so it’s a cost effective way of managing the situation.” 

Council in Taranaki Region, (Used for controlling algae species Anabaena & Microcystis)

“We have used ALPHASAN for about 5 years now and have always found it to be excellent for use in our RSW Tanks to enhance the quality of our fish and to extend their shelf-life. We ran out of this product last month so we used some Sodium Hypochlorite instead, which we had in stock. I was surprised at the difference between the two solutions, and never realised until then how rough Hypochlorite is on the fish!”

This was part of a Sequential Batch Reactor servicing a small town near Queenstown.

Notice the thick scum layer with pine needles on top of the clarifier, causing the distortion of the channels.

All the scum has now been digested & the effluent is clear. The final discharge was running at 10/10 BOD/SS.
