Involving some harsh operating conditions, wastewater treatment processes can pose a challenge for the manufacturers and operators of treatment equipment. Glass Reinforced Plastic (GRP) is an attractive, modern material that can deliver many benefits for the construction of equipment used in activated sludge processing plants.
Andrew Shedden, Head of Sales and Commercial at A&J Fabtech, here, has a look at the opportunities for this versatile material.
Sometimes referred to as fibreglass, GRP is composed of many millions of individual strands of glass, each one very fine, collectively formed into a fabric-like sheet. This is used to line a mould and is then set solid by the addition of a resin to which a catalytic chemical has been added so that it quickly hardens. Normally the GRP is applied in layers, with each one hardened before the next is added.
The result is a multi-layered material, shaped into a useful object that is strong and lightweight. Today we are all used to seeing GRP used in water tanks, canoes, and countless other everyday products. It is also a favourite material with engineers who are pushing the boundaries of technology. For instance aerospace engineers fit it in the latest supersonic, ultra manoeuvrable jet fighters, while civil and water engineers have found it really useful in developing a new generation of equipment for sludge processing plants.
A&J Fabtech is part of the A&J Group of Companies which produces and installs equipment for a wide range of industries. From components for the nuclear power industry to concrete mould manufacture and mechanical water treatment systems, the A&J Group possesses the necessary engineering to manufacture specialised equipment to customer designs and to complete bespoke turnkey projects.
Using in-house 2D and 3D CAD design and full materials traceability, coupled with extensive NDT (Non Destructive Testing) and inspection regimes, A&J can guarantee the quality of its equipment and project management skills for even the most critical of applications.
Around a sludge processing plant A&J Fabtech will recommend the best type of equipment for each individual situation. For instance it may recommend GRP for water and sludge processing equipment such as diffusor drums, energy dissipating drums, launder systems, McKinney baffles, scum boards, Stamford baffles, tank covers, weir boards, to name just a few.
The advantages of GRP can be summed up below:
A&J Fabtech’s ability with and understanding of all the major materials of construction means it can identify the optimum solution for each installation. It considers GRP to be a versatile material that can be used in a wide range of installations, often as a direct replacement for more expensive traditional solutions. Furthermore, for one-off projects it can provide a quick, cost effective and easy solution to almost any job.
