Introduction
I am a Senior Research Scientist (WASH) at the Water Sanitation & Hygiene Research & Development (WASH R&D) Centre, UKZN focussing on applied research on sanitation (decentralised approaches and non-sewered systems) and standards.

The design principles of decentralised wastewater treatment systems (DEWATS) make them a practical sanitation option for municipalities to adopt in fast-growing cities in South Africa. Since 2014, a demonstration-scale DEWATS with a modular design consisting of a settler, anaerobic baffled reactor (ABR), anaerobic filter (AF), vertical down-flow co...
Thyone neofusus Deichmann, 1941, Thyone adinopoda Pawson & Miller, 1981and Havelockia obunca (Lampert, 1885) are referred to the genus Sclerothyone Thandar, 1989, and a taxonomic key is provided to all species currently contained in the family Sclerothyonidae Thandar (sensu Smirnov 2012). Since the nomen Neothyone in the family Thyonidae (sensu Smi...
The Engineering Field Testing Platform (EFTP) was designed to provide an opportunity for technology developers (TDs) to test non-sewered sanitation prototypes in the eThekwini Municipal Area (Durban), South Africa. Between 2017 and 2020, 15 sanitation systems were tested in informal settlements, peri-urban households, and other ‘real world’ setting...
The presence of micropollutants, such as pharmaceuticals and personal care products, in surface and ground water has escalated globally, leading to adverse effects on aquatic organisms in receiving waters. Untreated or inadequately treated wastewater is the main source of micropollutants entering the environment. In South Africa, the consumption of...
These guidelines have been developed under a South African Water Research Commission (WRC) funded project to develop guidance on how to demonstrate and test innovative sanitation systems in real world environments prior to manufacture and commercialisation. The guidelines have been written for local technology and commercialisation partners (LTCPs)...
Thandar & Arumugam (2011), in their erection of the new dactylochirotid family Cucumellidae, inadvertently omitted to designate its type genus. This error is here rectified and Cucumella Heding (in Ludwig & Heding, 1935) is designated the type genus of the new family Cucumellidae to comply with the requirements of Article 61 of the International Co...
Several specimens of holothuroids in the collections of the Natural History Museum, U.K., identified as Rhopalodina la-geniformis or simply Rhopalodina sp., were re-examined. Amongst these only the holotype of R. lageniformis is referable to this species. Of the four specimens misidentified as R. lageniformis, two are re-identified as R. parvalamin...
A new species of Cucumella, C. triperforata, with simple, digitate tentacles is described from deep waters off the east coast of South Africa. Since C. triplex, the type species of this genus, also has simple, digitate tentacles, the genus Cucumella together with its type species is removed from the Dendrochirotida amd re-assigned to a new family,...
This paper records several species of holothuroid echinoderms dredged from shallow waters of the Angolan-Namibian coastline by the Leibniz Institute for Baltic Sea Research Warnemünde in Germany. Altogether seven species are dealt with, including five new species, of which one is referred to a new genus Lanceophora. The new species include two in t...
Questions
Question (1)
I have a demonstration-scale horizontal flow constructed wetland treating nitrified domestic effluent. The factor affecting denitrification is high DO (greater than 1.5 mg/L) within the bed and measured in the HFCW effluent. The CW is impounded to improve the hydraulic retention time in the bed. However, this has resulted in temporal surface water accumulation during high loadings. I suspected that the high DO could have been due to loosely packed gravel media within the CW but could the temporal flooding result in diffusion of atmospheric oxygen into the bed thus promoting natural aeration? The CW is fully planted Typha capensis and Cyperus sexangularis.
