Direct Acid Dosing
The Heron direct acid dosing system is used for the acidification of water to control pH. The direct acid dosing system acidifies the water as it is pumped into a water storage tank.
Accurate pH control is difficult to achieve. Long chemical reaction times are involved and a large proportion of acid is required to remove carbonates. The consequence is that the pH will rise over time. The Heron direct acid dosing system addresses these issues and provides you with a safe and reliable solution for the acidification of water in storage tanks.
The Heron direct acid dosing system is suitable for water storage tanks with sizes ranging from 20,000 Litres to 500,000 Litres. The direct acid dosing comes in two sizes. The MPD8-2i catering for input flows of up to 20,000 Litres/hour and the MPD8-9i for flow rates up to 40,000 Litres /Hour.
The system is particularly suitable for applications requiring low pH values, down to pH 4.5. The system is also intrinsically fail safe and minimises user handling of acid
Features
The Heron direct acid dosing has the following features:
- Doses the water as it is pumped into the storage tank and doses the storage tank.
- A unique algorithm is used to determine the acid dosing.
- Venturis are used to dose acid providing a rugged design with minimum moving parts.
- No seals are in contact with concentrated acid and there is no foot valve in the acid tank
- Concentrated 60%-70% acid can be used and no dilution of acid is required
- Changing acid barrels is simple and safe. The acid line is simply dropped into the new barrel.
- Can be connected to a Heron irrigation controller
System Configuration
A fill pump is required to pump water through the dosing system. The buffer tank system is intrinsically safe. Water passesthrough the rig once, and is dosed once to the correct level.
The fill pump must be capable of delivering the full irrigation flow rate.
For the smaller size system, the fill pump can be optionally fitted as part of the dosing rig.
