ATTRIBUTES
These treatment technologies will,
once implemented, reduce the volume
of waste disposed to landfill, limit the
further generation of leachate in the
landfill environment and improve the
quality thereof. Oils and some brines
currently destined for landfill disposal
will also be recovered for further use.
WASTE TREATMENT OPTIONS AND PROJECTS
In support of EnviroServ’s drive towards sus-
tainable waste management, EnviroServ has
invested in various alternative waste treat-
ments such as Effluent Treatment, Oil Sepa-
ration, Evaporation, Freeze Crystallisation,
In-vessel Composting, Mechano-chemical
Destruction and Micro-encapsulation. Some
of these technologies have been implement-
ed and others are planned for the future. This
is in line with the restrictions listed in the Na-
tional Norms and Standards for the Disposal
of Waste to Landfill.
Effluent Treatment Plants (ETP) are offered at the Aloes, Holfon-
tein, Nyamasoga and Shongweni Landfill Sites. The ETPs make use
of ultra-filtration (UF) and reverse osmosis (RO) membranes that con-
centrates the contaminants into a brine stream and produces a clean
permeate. The brine will be further treated at the Micro-Encapsulation
Plant or disposed of via current disposal processes to landfill. The fi-
nal clean permeate meets discharge standards for river or sewer as
required.
A Freeze Crystallisation Plant (FCP) has been constructed at the
Holfontein Landfill Site. The plant uses a number of freeze processes
to progressively precipitate out salts. The plant produces a clean per-
meate and various brines which are disposed of or recovered for sale.
Oil Separation Plants (OSP) will cater for the treatment of water
contaminated with oil. The OSP will use an Ultra Filtration Membrane
to concentrate the oil into a product stream and produce a permeate.
The recovered oil will be sold while the permeate will be treated in the
ETP, if required.
In-vessel composting is offered to increase the composting rate
by using a vessel with regulated temperature and moisture conditions.
Mobile Composting Units (MCU) and composting in windrows are of-
fered at various landfill sites. MCUs have been successfully installed at
various clients, one of them being BAT in Heidelburg.
