Get QuoteAs a twin-island nation in the Eastern Caribbean, Antigua and Barbuda faces distinct environmental challenges and industrial transitions. Due to the lack of major natural freshwater rivers, the nation relies heavily on sea-water desalination plants (such as the Crabbs Reverse Osmosis plant) to meet domestic and commercial water demands. The processing and treatment of desalination brine, backwash residues, and mud slurries require high-performance dewatering solutions like recessed chamber filter presses to separate solids and protect sensitive marine habitats from contamination.
Simultaneously, Antigua's luxury tourism sector generates substantial volumes of municipal wastewater. The Department of Environment strictly regulates sewage treatment and effluent discharge parameters. Modern biological treatment facilities utilize recessed filter plates to consolidate sludge cakes, minimizing volume for transportation and maximizing reclaimed water rates for landscaping and irrigation.
In the agricultural and processing sector, Antigua's iconic rum distilleries and small-scale agro-businesses require high-grade liquid-solid separation systems. Clarifying molasses, filtering yeast cells, and treating highly acidic distillery stillage demand filter plates with superior chemical stability and thermal resistance—qualities native to Jovios’ engineering-grade polypropylene compositions.
Industrial operations globally are shifting away from energy-heavy centrifuges toward highly efficient, physical cake filtration models. Here is what is driving the market forward.
Transition from cast iron and wood plate frames to virgin polypropylene blocks. These plates provide resistance to chemical attacks, lower weight, and offer exceptional durability against hydraulic fatigue under high pressures.
Modern plants are adopting secondary squeeze membrane plates. By injecting air or water behind the membrane, filter presses can achieve dry solids contents of up to 75%, significantly lowering subsequent thermal drying costs.
Health and safety regulations globally demand leak-proof operations. Sealed CGR plates utilize synthetic elastomer gaskets built into the perimeter grooves of the filter plate, stopping acid mist or odorous gas leaks.
Select the right filter plate configuration for your industrial plant. Jovios manufactures plates ranging from 320mm to 2000mm in size, accommodating pressures up to 2.5 MPa.

How our plate designs solve real-world processing problems, maximizing solids recovery and water reuse efficiency.
Desalination backwash water and clarification sediments contain micro-solids. Utilizing our high-pressure 15-bar recessed PP plates, plants can compress this slurry into stackable, bone-dry filter cakes that can be safely landfill-disposed, preventing environmental pollution.
Effluent from rum production has low pH and high COD values. Our gasketed chamber filter plates (CGR) create an airtight seal that holds up under hot, acidic cycles, facilitating the separation of yeast cell hulls from waste streams.
Sludge management at treatment facilities in St. John's is optimized using Jovios membrane plates. Secondary squeeze stages reduce sludge water content, saving transport and disposal costs.

Recessed chamber filter plates merge the plate and frame into a single unit, featuring a recessed area on each side that forms a chamber when closed. This design offers two main benefits: increased structural strength, allowing for filtration pressures up to 15-20 Bar, and easier cake discharge. Without separate frames, automatic plates can be shifted quickly to let cakes drop, which helps lower labor costs and shortens cycle times.
Coastal and marine environments feature high salinity, which causes rapid corrosion in traditional cast iron and metal filter components. Copolymer Polypropylene (PP) is highly resistant to saltwater, brine, acids, and alkalis. Additionally, PP is lightweight, high-strength, non-toxic, and has low water absorption, making it suitable for wastewater management and environmental protection in tropical island climates.
CGR stands for Caulked, Gasketed, Recessed. CGR plates feature an O-ring groove around the sealing edge and filtrate ports, where rubber or elastomer gaskets seal the chamber closed. This system prevents capillary leakage and helps stop odors or corrosive vapors from escaping. It is recommended for applications requiring zero leakage, such as industrial acid filtration or odor-sensitive municipal waste processing.
Sizing depends on key slurry factors: solid concentration, density, liquid chemical composition, temperature, and target processing time per day. Our engineering team calculates total chamber volume (liters) and filtration area (square meters) based on these inputs to ensure the system handles your target cake thickness during each cycle.
Jovios maintains quality control through automated machinery and comprehensive testing. We use high-tonnage molding machines to shape each PP plate, preventing internal stresses. Finished plates undergo rigorous flatness checks and pressure tests up to 1.5 times their rated limit to ensure they resist warping and cracking over years of service.
