Ef­flu­ent sys­tem launched

Matamata Chronicle - - News - By ABBY BROWN

A new ef­flu­ent sys­tem de­signed in Mata­mata could put the farm­ing town on the map in terms of in­ven­tive­ness af­ter its com­pany launched the prod­uct, which will do away with the need for an ef­flu­ent pond, at the Na­tional Fiel­d­ays this week.

The Forsi Ef­flu­ent Re­cy­cling Sys­tem will change cur­rent farm­ing prac­tices by elim­i­nat­ing the need for ef­flu­ent ponds, help­ing farm­ers avoid costly com­pli­ance fines while also re­duc­ing wa­ter wastage and waste con­tam­i­na­tion. Elim­i­nat­ing the ef­flu­ent pond will mean that less land is wasted, Forsi op­er­a­tions and mar­ket­ing manager Craig Hawes said.

Less wa­ter will be used, which will be good for farm­ers who are un­der the Waikato re­gional plan vari­a­tion num­ber six for wa­ter al­lo­ca­tion. Less power will be used to pump out wa­ter too.

The Forsi Ef­flu­ent Re­cy­cling Sys­tem, housed in a 40 foot con­tainer for ease of on­site in­stal­la­tion, works by tak­ing raw cow ef­flu­ent through a large sand trap and over the Forsi Slope Screen Sep­a­ra­tor. From here it en­ters a suspended solid re­moval sys­tem. It is then pol­ished and ster­ilised to pro­duce clear, pathogen free wa­ter. This wa­ter can then be reused to wash down the yard af­ter the next milk­ing, go to the ir­ri­ga­tor or go into a wa­ter­way.

The solids, which Hawes said would ‘‘look like choco­late mousse’’, are held in a bunker where they com­post down. The farmer will even­tu­ally be able to ei­ther spread it as a fer­tiliser or mix it into the soil to ben­e­fit the crops. This won’t leach or run off so it is not detri­men­tal to the en­vi­ron­ment.

The new sys­tem will be launched this week’s Fiel­d­ays at site F30.
