Walpole LTP chemical dosing system refurbishment is the third upgrade that Phoenix is undertaking for Viridor at its existing Leachate Treatment Plants. The new reinforced concrete support base has been constructed and the sodium hydroxide storage tank has been delivered and fixed into place. Viridor is currently undertaking an assessment for a power supply upgrade. Once that is complete Phoenix will return to site and install the new power supply, upgrade the LTP SCADA system and complete commissioning of the new chemical dosing system. Included in the refurbishment works, Phoenix has installed an innovative safe means of access to the existing treatment lagoon floating aerators for maintenance.
