ABOUT WOODLANDS

Woodlands Dairy employs over 1,400 people and prides itself on an innovative spirit, agility and speed in new product development, and excellent customer service. The product range includes various cheeses, butter, cream, custard, flavoured milks, and amasi, a fermented milk similar to cottage cheese that is very popular in Southern Africa. The company also produces extended shelf life (ESL) fresh milk and is one of the largest manufacturers of UHT milk in South Africa, marketed under the brand First Choice.

The milk processing factory is located along the South African Garden Route, right in the heart of the Eastern Cape dairy region. As a local fresh milk processor that produces and packages high-quality dairy products, Woodlands wants to take full responsibility for the environmental impact of its operations. The farming methods should not only have a minimal impact on the environment, but should also be animal-friendly and boost public support for dairy farming.

Water management

The Woodlands Dairy factory comprises a milk sterilisation and packaging plant, as well as a cheese factory. In 2012, the company adopted an environmental management system (EMS) to improve its energy efficiency and waste management, and to decrease both its emissions and use of natural resources. The EMS complies with the international ISO 14001 standard and aims to minimize operational impacts on the environment, ensure legal compliance, and continuously improve the company’s environmental performance.

The most significant risks identified as part of the EMS process included the liquid effluent management, waste management and recycling, as well as water consumption. Recycling water with an on-site wastewater treatment plant was assessed to be the most pressing concern. As part of improving its waterbalance, Woodlands Dairy commissioned a  Memthane® system in March 2017. Around 60 percent of the dairy plant’s wastewater is now being recycled. This not only means a considerable decrease in effluent discharge but, perhaps even more importantly in an arid climate with increasingly scarce reserves, also a 60 percent decrease in the demand for fresh water.

背景

为保证供应安全可靠的饮用水,莫斯科市约在 10 年前便增添了大型饮用水工厂。以超滤(UF)技术为核心,莫斯科西南部的饮用水工厂是欧洲最大的超滤工厂,处理能力达 250,000 m3 /d.

Memthane® is an anaerobic membrane bioreactor (AnMBR) process which contains the micro biological anaerobic process (excludes oxygen), this technology turns medium to high-strength wastewater into energy and clean water that can be directly reused or discharged. The system was developed in a cooperation between Veolia subsidiary Biothane and Pentair. The Biothane reactor processes the wastewater and generates biogas. Pentair’s X-Flow membranes separate the sludge and produce clean water. The sludge from the reactor remains rich in nutrients and can be used by local farmers as fertiliser. Woodlands Dairy calls its new Memthane installation a Resource Recovery Plant, or RRP. Whereas all effluent from the various production processes used to end up in a combined effluent sump, the new wastewater plant is capable of processing 1.5 MLD. At a later stage, this is set to be upgraded to 2 MLD. The incoming feed stream with about 10,000 ppm of COD is turned into a high quality effluent with less than 100 ppm. As dairy processing is an energy-intensive operation, the biogas is a welcome bonus used to heat the on-site biogas boiler.

In the Woodlands Dairy factory, pretreatment of the feed stream is limited to pH adjustment and an equalisation tank. In peak season the plant can handle1,500 m3 of wastewater containing about 12 tonnes of COD. The ultrafiltration (UF) part of the plant consists of four separate skids with 26 modules each, applying Helix membranes to maximize UF efficiency. All of this water is reused, most of it after an additional dual Pass RO polishing stage as the only necessary post-treatment. Memthane significantly reduces wastewater treatment costs compared to conventional technologies. The pore size of the membranes delivers a permeate free of suspended solids. At Woodlands Dairy, just as in other dairy operations around the world, Memthane has proven to be a robust and reliable solution.
