will be pumped out into the waste storage tank then the tank will be topped up with more fresh
water and used to supply water to the drum filter wash down. When the waste water from the
drum filter is pumped into the settling tank it will be dosed with Polyacrylamide to act as a
flocculent, this will allow the solids to settle to the bottom of the settling tank where it can be
pumped out into the waste storage tank.
