Econotreat VBB-P-2000



Econotreat VBB-P-2000  Advanced Secondary Treatment 2000L per day

Manufactured in Northland, the Econotreat is a leader in it’s class. Running off a single blower, the Econotreat delivers consistently high results ; while drawing consistently low amounts of power, only 1.3kwh per day. With proven nitrogen reduction at the National Testing Facility, it is one of the few systems permitted to be installed in restricted discharge areas, such as around the Rotorua lakes. In plastic modules, this version has it’s application in tighter and more challenging access.

The Treatment Process

Primary Chamber / Tank

Influent enters the chamber via the source whereby scum and solids capable of settling are separated from the raw influent. Primary treated effluent flows through a transfer port to the aeration tank. This primary tank will also act as a storage chamber for sludge returned from the Clarification Chamber.

Aeration Chamber

Water enters from the Primary Chamber. Air is introduced into this chamber via an air blower to create an environment for aerobic bacteria and other helpful organisms to consume the organic matter present. The aeration tank is designed in a manner to help prevent short circuiting of the wastewater to ensure extended aeration. Media is present in the tank to support the growth of bacteria.

Clarification Chamber

The Clarification chamber is essentially a quiescent zone where suspended particles/solids are settled out of the water. These particles are returned to the Primary chambers via a sludge return which aids in further biological reduction, denitrification and providing a constant food supply rich in microbes supporting the system through periods of limited flows.

Tank Specifications
Tanks are injection molded with UV stabilized polypropylene, which is suitable material for wastewater treatment containment meeting all the requirements of Section 4.3.3 of AS/NZS 1547:2012. These tanks have an expected lifespan of 50 years.
