How JIPL Helps Deal With Hazardous Waste

21/05/2018 By Gen Lynch

waste recycling, JIPL

Waste is a problem facing all of us – in more and more threatening proportions. Waste management is a global problem and something we all need to take seriously. Disposing of waste has huge environmental impacts and can cause severe problems. JIPL takes a serious approach to waste and can help tailor your waste management solutions.

JIPL has experience dealing with all kinds of waste, including hazardous waste.

Recently JIPL designed and implemented a waste management solution for ChemWaste to deal with their hazardous waste. JIPL designed and installed a recycling treatment plant for waste caustic. JIPL provided Chemwaste with a caustic recycling plant able to store wastes from aluminium extrusion plants around the country and clarify it, to provide a quality liquid caustic resource for resale.

JIPL worked closely with ChemWaste and other nominated ChemWaste personnel to ensure the objectives were met, and engineering and process details were agreed.
JIPL utilized their 25 years of experience of operating filter press technology and experience of this type of caustic wastes to ensure that the plant was delivered to ChemWaste’s specific needs.

ChemWaste follow sustainable business practices and keep the needs of people and the environment always firmly in mind. ChemWaste specialises in tailored waste disposal solutions and understands that customers have varying needs based around risk management, health and safety, service and cost. JIPL kept this in firmly in mind when designing the caustic recycling plant.

The overall concept for the waste management plant JIPL designed was to transfer the wastes from the aluminium extrusion plant’s die cleaning operations into a large storage tank to provide capacity for deliveries from the various aluminium extrusion plants. The liquid waste contains unused caustic and sodium aluminate as well as various metal hydroxide precipitates and particulates. The particulates are removed and the liquid is clarified using the filter press as the clarifier. The filter press is pre-coated using either lime or diatomaceous earth as the filtering media.
JIPL modified the existing filter press (membrane type) to provide the required functionality. The filter cake is back-washed to remove excess caustic so as to be able to dispose of the cake safely.
The resulting clarified liquid is mostly clear and contains very little contaminants and is, therefore, a higher value product and has an increased market value.
JIPL also designed a control system to automate the recycling plant so there is no need for an operator to ‘babysit’ the process. This ensures site productivity as well as safety for the operators.

JIPL used its process and design experience to create a better method of dealing with ChemWaste’s liquid waste. For more information on Jonassen Industrial Projects Limited and their project engineering and customized engineering services email: info@jipl.co.nz
