HUBER have provided the inlet works solution and/or the sludge thickening solution at most of the Nereda first of a kind in the water utilities – including Severn Trent, United Utilities and Anglian Water.

Standardised DfMA Inlet Works

The HUBER Complete Plant ROTAMAT® Ro5 – complete plant is an all-in-one inlet works comprising longitudinal grit separation – essential to guarantee the grit removal rates required by Nereda – grease removal and screenings in a single factory constructed unit.

This unit is serving both Scottish Water at Inverurie and Anglian Water at Great Dunmow.

Standardised DfMA packaged screens

A further inlet works innovation was also used at the first Nereda plant in United Utilities at Westnewton WwTW using the HUBER Micro Strainer ROTAMAT® Ro9. This project won two Water Industry Awards 2021 – the first for innovation across the whole project and secondly for the inlet works which HUBER developed with UU’s delivery partner Advance Plus – Delivering Efficiencies through productising complex products.

This inlet works design was developed in partnership for use across the whole of UU’s area – and can be replicated by any delivery partner – it has already been adopted by C2V+ and represents a standard solution, largely constructed off-site comprising HUBER Ro9 screens in tanks with a by-pass.

Standardised DfMA Sludge thickening

The HUBER Disc Thickener S-DISC has long been the go-to sludge thickening plant for smaller sewage works based on its, robust operation and design, exceptionally long life and low cost. The ability to package the equipment onto a plug and play skid, assembled at HUBER’s Chippenham workshop means it fits perfectly with Royal Haskoning’s DfMA philosophy. The first time Nereda sludge was treated in the UK was at Anglian Water’s Great Dunmow site where the skid mounted S-DISC was fitted at the back of the package HUBER Ro5 inlet works and the package Nereda plant.

The S-DISC took the Nereda sludge in its stride and has been installed at Nereda plants at Failsworth (UU) and Radcliffe-on-Trent – for Severn Trent Water where the S-DISC is widely used.

Larger Standard sludge thickening solutions

Due to the HUBER process security around thickening sludge, including Nereda, the HUBER Rotary Screw Thickener S-DRUM are now used on larger Nereda works such as Kendal WwTW (103,000PE) and Blackburn (320,000 PE).

We are excited to support our customers on new plants and are keen to be involved in the early stages of planning a plant to ensure all areas of the process are considered. With a range of trial units available, help with onsite trial / development work can be undertaken.
