New Factory Upgrade, Sopura, Westake

A2V assisted Sopura in upgrading their new premises to a custom designed chemicals manufacturing facility as a turnkey project. Our scope of work included the design and supply of following:

1. A platform supporting mixing tanks for batch mixing of various chemicals.
2. An epoxy lined bund to contain any corrosive chemical spills from the manufacturing process.
3. Hoods and extraction systems for ventilation corrosive, toxic fumes
4. An effluent plant for pre-treating effluent prior to disposal to the municipal sewer.

Chemical Batching Facility

Protea Chemicals, Blackheath

A2V recently embarked on a turnkey project to upgrade Protea’s Blackheath manufacturing facility.

Phase 1 of the project , completed recently,  was to upgrade the offloading facility which receives bulk deliveries of concentrated sulphuric acid. A new emergency bund lined in polyethylene anchor knob sheet was constructed and the roadway replaced in reinforced concrete with a heavy duty epoxy system from Sika.

The existing steel oxidizing tanks were also replaced in polyethylene with a galvanized steel support frame for the mixer units.

Indigo Brands Water Security

In response to the recent water crisis in Cape Town, A2V were requested to assist in identifying a solution to ensure Indigo’s water supply in the event of disruption to supply. in addition, the City’s pressure management programme has also reduce supply pressure to the point where parts of  Indigo’s facility were no longer receiving water.

The study included test well points, sampling and evaluation of ground water quality through to treatment and recycling of effluent. The solution implemented included a 600kL reservoir fed by municipal water and booster pumps to feed it into the factory and offices. The intention being that in future the municipal supply can be supplemented with treated rainwater, groundwater or effluent. A2V for responsible for the implementation and project management as well.

Protea Chemicals – Upgrade of Acid Storage Facility

The newly AKS lined 98% sulphuric acid bund

A2V were appointed to upgrade two Sulphuric Acid facilities at Protea Chemicals’ Killarney Gardens site. The existing facilities had been largely destroyed by acid attack over the years an had to be largely rebuilt.

A2V carried out the conceptual design in conjunction with Proteas’ engineers, after which A2V completed the structural design. and project manged the implementation of the project.

The bunds comprised reinforced concrete wall and floors lined in polyethylene anchor knob sheeting. The Anchor Knob Sheets(AKS) used were UV stabilised 3mm thick polyethylene sheets which are stubbed with knobs that are cast into the concrete walls and slab soffits. AKS can also be grouted onto floor slabs and walls of existing structures.  Once the concrete is partially cured the form work is removed and the joints between AKS sheets are sealed by plastic extrusion welding. 

This method of lining proved to me more cost effective than some of the epoxy lining systems considered, despite the more labor intensive nature of the installation.
