Evaporation, Crystallization & Waste Water Handling

• For lake brine and solar salt upgrading — food-grade, technical and pharmaceutical salt production.
• Capacity: 500 l/h – 50 m³/h (evaporated water), crystalline product 100 kg/h – 20 t/h.
• Technology: Multiple Effect Evaporation (MEE) or Mechanical Vapour Recompression (MVR) — minimises energy cost.
• Process: raw brine pre-treatment → multi-effect evaporation → crystallisation → washing → drying → packing.
• Key feature: from raw brine to packed product in one line; modular for phased expansion. Relevant for Tanzania's inland salt operations (Uvinza, Lake Eyasi) and Kenya's Lake Magadi.

• For mining and industrial effluents containing metal sulphates, chlorides and organic contaminants.
• Process: chemical pre-treatment → heavy metal removal → filtration → evaporation → crystallisation of recoverable salts.
• Technology: Forced Circulation Evaporator / Crystalliser (FC), Falling Film Evaporator (FFE) — selected per contamination level and scaling risk.
• Output: clean process condensate (reusable on-site), crystallised salts (marketable), zero liquid discharge.
• Key feature: handles high contaminant loadings; eliminates liquid purge entirely. Relevant for mining operations in Tanzania, Zambia and DRC where water discharge is regulated.

• For salt solutions, chemical concentrates, fertilizer liquors and industrial process streams.
• Capacity: 500 l/h – 50 m³/h (evaporated water).
• Evaporation type: multi-effect (MEE), mechanical vapour recompression (MVR) or thermal vapour recompression (TVR).
• Material: stainless steel, duplex, titanium — per corrosivity of feed.
• Key feature: MEE and MVR cut specific energy consumption significantly vs. single-effect; modular design allows phased expansion. Suitable for energy-constrained sites in East Africa.

• For salts, fertilizers, chemicals, pharmaceuticals — including ammonium sulphate, potassium chloride, sodium sulphate.
• Capacity: 100 kg/h – 20 t/h (crystalline product).
• Types: Forced Circulation (FC), Draft Tube-Baffle (DTB), Flash Crystalliser — selected per target crystal size and purity.
• Crystal size: 0.1–5 mm (adjustable).
• Key feature: DTB produces larger, more uniform crystals; recrystallisation achieves purity >99.9% for pharmaceutical or reagent-grade product.
