000874672 520__ $$aCharge-stabilized suspensions have interesting static and dynamic features, reflected in properties such as the suspension osmotic pressure, generalized sedimentation coefficient and viscosity. These properties are determined by electro-steric and (partially) by electro-hydrodynamic interactions. Due to the large size asymmetry between the colloidal macroions and the small microions, the degrees of freedom of the latter can be integrated out, resulting in an effective one-component interaction potential describing microion-dressed colloidal quasi-particles. We present a comparison, and partial extension, of various methods of calculating effective colloidal interaction parameters including effective charges and screening constants [1]. Additionally, we discuss osmotic suspension pressure calculations for dispersions in Donnan equilibrium with a salt ion reservoir. We discuss methods including cell-models [2,3], renormalized jellium models [4], and multi-colloid-centered mean-field models [5,6]. The pros and cons of the various methods are assessed by comparison with primitive model based computer simulations.References[1]	M. Brito, J. Riest, A. Denton and G.
