pH neutralisation is essential before advanced biological treatment. Reynolds & Bauhm systems handle the variable loads
Available footprint often dictates process selection. Containerised systems, vertical stacking, and high-rate processes maximise treatment capacity in limited space.
Capital expenditure and Operating expenditure budgets influence technology choice, material specification, and automation level. Life-cycle costing reveals the true cost difference between options.
Diurnal, seasonal, and production-driven flow variations require equalisation and flexible process capacity. Fixed-rate systems fail during peaks and waste energy during troughs.
Discharge consent limits, reuse quality standards, or environmental permits define treatment depth. Over-treatment wastes money; under-treatment risks prosecution.
Operator skill level, shift cover, and spare parts inventory influence equipment selection. Simple robust systems suit remote sites; sophisticated plants need trained technicians.
Design for 20-30% flow growth avoids early replacement. Modular construction, oversized pipework, and spare tank connections make future expansion straightforward and economical.
Yogurt plant treatment systems achieve >90% BOD removal and reliable compliance with discharge requirements, even with t
Achieves 85-98% COD reduction depending on process selection and influent characteristics. Anaerobic pre-treatment followed by aerobic polishing delivers the highest removal rates.
Total suspended solids reduced to below 10-30 mg/L through coagulation, flocculation, and physical separation. Lamella and DAF clarification provide consistent solids removal.
Fat, oil, and grease reduced to below 5-15 mg/L using CPI separators, DAF, and biological degradation. Pre-treatment protects downstream processes from fouling.
Ammonia-N below 5-10 mg/L and total phosphorus below 1-2 mg/L achieved through biological nitrification-denitrification and chemical precipitation with ferric salts.
Effluent pH maintained within 6.5-8.5 through automated acid/alkali dosing with inline probe control. Buffer tanks prevent pH shock to receiving waters.
Systems designed for peak flows of 1.5-3x average daily flow with hydraulic capacity to handle diurnal variation without bypass or loss of treatment quality.

Mix with higher pH wastewater (sweet whey, milk) to neutralise before treatment.
Reduces neutralisation chemical requirements
Acidic streams (pH 3.8-4.6) require neutralisation before advanced biological treatment. Use equalization tanks to blend acidic and alkaline streams.
Fruit preparation waste contains 10-30% sugar, creating rapid BOD spikes. Extended aeration or SBR systems recommended.
High bacterial content can affect treatment process. Pre-screening and controlled addition to biological system recommended.
High protein content combined with surfactants from CIP creates foaming. Antifoam systems and proper aeration design essential.
